La Crosse Institute For Movement Science (LIMS)
Thomas Kernozek, PhD, Director
The Institute was created in 2005 at the University of Wisconsin-La Crosse in the Department of Health Professions
in the Health Science Center. The Institute brings together
scientists and clinicians of various disciplines seeking new
knowledge related to human movement, factors related to
injury, the foundations of therapeutic exercise used int the
treatment and rehabilitation of injury.
Each year over 40 students from graduate and undergraduate programs across the UW-L campus are involved in
laboratory research including Physical Therapy, Exercise
and Sport Science, Physics, and Biology. High technology
funding from the State of Wisconsin supports 8 Physics
Biomedical student internships in the lab.
The clinical biomechanics laboratory has a national reputation from published and presented work.
Current Projects
 Understanding mechanisms of non-contact ACL injuries in females.
 Evaluating patellofemoral joint stresses with running mechanics of females with patellofemoral pain.
 Examining the effects of multifrequency vibration on blood flow and
muscle activation.
 Evaluating changes in bone stresses during running in those with a
previous history of stress fracture.
LIMS Scientists
LIMS acquires HBM System
Chris Durall, DPT, ATC, MSPT (UW-La Crosse Health Center)
John Greany, PT, PhD, Exercise Physiologist, (Health Professions)
LIMS partnered with Motek Medical (Netherlands) to
evaluate HBM system for the quantitative assessment of
human movement.. The HBM system uses motion capture, external forces and muscle activation to estimate
muscle forces in real time. These measurements allow
researchers to better understand tissue stresses of
movement leading to acute/overuse injury or muscle
force generation during rehabilitation exercises. The
system is located in the 2,250 square foot clinical biomechanics laboratory.

LIMS Reputation Continues to Rise
LIMS in the Department of Health Professions enabled the
Physical Therapy Program to reach in strategic goal of publishing 25 peer reviewed papers over a 3 year span. LIMS
researchers accomplished this in two!!! This distinguishes the
Physical Therapy program in the upper tier of scholarly output
nationally in physical therapy education. This could not have
been done without dedicated faculty and student scholars.
Congratulations on a job well done!
